Troubleshoot Activity With Log Monitor; Perform Advanced Log Monitor Operations - VMware THINAPP 4.6 Manual

ThinApp User's Guide
The generated log files can be large and over 100MB depending on how long the application runs with Log
Monitor and how busy an application is. The only reason to run Log Monitor for an application is to capture
trace files. Trace files are critical for troubleshooting problems by analyzing and correlating multiple entries
within the trace file.

Troubleshoot Activity with Log Monitor

You can use Log Monitor to perform basic troubleshooting.
Troubleshoot ThinApp logs
1 Shut down the captured application to investigate.
2 On the computer where you captured the application, select Start > Programs > VMware > ThinApp Log
Monitor.
To start Log Monitor on a deployment machine, copy the log_monitor.exe, logging.dll, and Setup
Capture.exe files from C:\Program Files\VMware\VMware ThinApp to the deployment machine and
double‐click the log_monitor.exe file.
3 Start the captured application.
As the application starts, a new entry appears in the Log Monitor list. Log Monitor shows one entry for
each new trace file. Each file does not necessarily correspond with a single process.
4 End the application as soon as it encounters an error.
5 Generate logs for each trace file you want to investigate.
a Select the .trace file in the list.
b Click Generate text trace report.
Child processes that the parent process generates reside in the same log. Multiple independent processes
do not reside in the same log.
ThinApp generates a .trace file. Log Monitor converts the binary .trace file into a .txt file.
6 (Optional) Open the .txt file with a text editor and scan the information. In some circumstances, the .txt
file is too large to open with the text editor.
7 Zip the .txt files and send the files to VMware support.

Perform Advanced Log Monitor Operations

Advanced operations in Log Monitor include stopping applications or deleting trace files. If an application is
busy or experiencing slow performance with a specific action, you can perform suspend and resume
operations to capture logs for a specific duration. The resulting log file is smaller than the typical log file and
easier to analyze. Even when you use the suspend and resume operations, the cause of an error might occur
outside of your duration window. Suspend and resume operations are global and affect all applications.
For more information about using these options, contact VMware support.
